Michalina Olszańska (born 29 June 1992 in Warsaw) is the daughter of actress and singer Agnieszka Fatyga and actor Wojciech Olszański.
She is a Polish actress, writer, violinist and singer.
She started playing violin at 4 years old and when Michalina got into music school, they all believed that her extraordinary talent would result in a violin career.
But she had a much bigger appetite. Her mom introduced her to the world of art making puppet shows and familiarizing her with ancient beliefs, tributes and Polish legends. Her dad taught her horse back riding.
Finally, at 11-years-old Michalina had her debut on stage with her mother Agnieszka Fatyga in front of a big audience. Her mother would have rather wanted her to pursue a career of medical or legal studies but Michalina, however, was attracted to art and the environment she was constantly around while growing up.
By the time of adolescence she had written two novels. In November 2009 she published her debut novel "The Child of the Stars of Atlantis", in 2011 another. "Enchanted". The girl was now making lyrics, until she finally began composing music.

More and more often, you could watch the family perform together on stage. After taking her high school diploma at music school she left off to study at Aleksander-Zelwerowicz National Academy of Dramatic Art. In the meantime Michalina had already taken part in many photo sessions and as a model she quickly gained recognition.
At the same time, the producers of the series "Color of happiness" noticed her. She played a singer in Tina when she was only 18 years old. She gained international fame through the films "Daughter of Dancing" and "I, Olga Hepnarova". For her role in I, Olga Hepnarová she received the Minsk International Film Festival Award for best leading actress in 2016 and the Czech Film Critics' Award for best actress in 2017.
Thanks to her knowledge of Russian she got a leading role in the film "Matilda", which before the premiere in Russia caused a lot of emotions and opposition. She played the mistress of Czar Nicholas II, Mathilda Krzesińska. "It's the role of a ballerina, a princess in beautiful dresses, a totally good character, a beloved emperor. It was a scandal because Nicholas II is a saint in the Orthodox Church and can not have a lover - she said in interviews.

She portrayed one of the most famous women in Hollywood, who, as Pola Negri († 90), conquered the hearts of celebrities such as Rudolf Valentino († 31) and Charlie Chaplin († 88).
